What determines how far the bookport will jump back when you hit a key of any kind. It seems as if sometimes it jumps quite a ways back and you really have to listen for a while to get back to where you were. This seems to be a little bit worse with the newest beta. Also The times when the bookport is all of a sudden dead when I have just turned it off and turned it back on seem to be a little worse too. In best case scenario I just hit reset, otherwise I have to take out a battery for a second. This is not a big thing, just an inconvenience, and I doubt it is something you can replicate, but I have noticed it. Kurt.
